UDACT Instruction Manual PN 50050:H 09/16/2002
115
Appendix J: NFS-3030
General
The UDACT is capable of reporting up to 2,040 points when used with the NFS-3030 (1,980
Addressable devices plus 60 zones or 1,800 Addressable devices plus 240 zones) The first 568 points
can be programmed using the Type Mode feature (refer to "Type Mode" on page 55). All points greater
than 568 can be transmitted only as fire alarm points. For the UDACT to report a supervisory point to
the central station, both the FACP and the UDACT must have the point programmed as supervisory.
Failure to program the panel or UDACT correctly will result in a fire alarm signal being transmitted to
the central station.
Note:
The UDACT does not support voice and burglary options when used with the NFS-3030. Refer to the
NFS-3030
Installation Manual
for additional restrictions and more information.
Mounting
The UDACT may be mounted in the NFS-3030 control panel enclosure or be mounted remotely using
an ABS-8R
or UBS-1 enclosure placed in conduit and within 6000 feet (1828.8 meters) of the control
panel.
For mounting instructions see "Remote Installation" on page 22 or
"Internal Installation" on page 20
.
Wiring
CAUTION:
Remove all power from the control panel by disconnecting AC and batteries
before
making any connections to prevent personal and/or circuit damage.
Connections
Refer to Figure 31 on page 116.
Connect the communication line between the EIA-485 terminal block on the CPU-3030 and TB1
terminals 3 and 4 on the UDACT, being certain to observe polarity.
If no other devices are connected to the EIA-485, install a 120 ohm EOL resistor across UDACT
TB1 terminals 3 and 4.
Connect the
Ground Wire (PN 71073, provided)
from the UDACT
EARTH
terminal on TB3 to the CHS-4
Chassis or to a solid building earth ground.
Connect 24 VDC filtered, regulated power from the CPU-3030 or AMPS-24/E (Main Power Supply) to
TB1 terminals 1 and 2 on the UDACT.
Notes:
1. Recommended wire is 12 AWG (3.25mm
2
) to 18 AWG (0.75mm
2
), twisted pair, shielded cable.
Connect only one end of shield: a) shield may be connected to cabinet (earth ground) at fire alarm
panel, or b) shield may be connected to TB1 Terminal 5 (Shield) at UDACT as shown in Figure 31
Note:
The shield end that is not connected should be insulated to prevent accidental grounding. Do not connect both
ends of shield under any circumstance since a ground fault may result.
2. Conduit is recommended for external wire runs. Consult local building codes.
3. Refer to "Specifications" on page 13 for power requirements.
